MACHINE FOR STONING WATCH-PLATES, C.

SPECIFICATION forming part of Letters Patent No. 231,275, dated August17, 1880.

Application filed July 17, 1880.

To all whom it may concern Be it known that I, ALFRED H. OLEAVES, ofSpringfield, in the county of San gamon and State of Illinois, haveinvented a new and valuable Improvement in Machines for StoningWatch-Plates, Grinding Flat Steel-Work, 850.; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side View of myimproved machine, and Figs. 2 and 8 are details.

This invention has relation to improvements in machines for stoningwatch-plates, grinding flat steel-work, lapping oil-stones and bones,and securing fiat surfaces on any kind of watch or other work.

The nature of the invention will be hereinafter more fully set forth.

In the annexed drawings, the letter A designates a table raised asuitable distance from the floor, and having secured thereon a trough,B, containing a bed or lap, 0, upon which the work is pressed insmoothing it.

D indicates a lever fulcrumed at one end to the rafters, joists, or roofof a shop, and having suspended from its other end a connecting-rod, D,which extends through a slot in the table A, and is connected to atreadle, E, arranged under the same.

The lever D is supported from below by a spring, S, arranged on a headedbelt, 0, extending from below through said lever and secured to the roofof the shop. By the depression of the treadle the lever is drawn downand spring S compressed, so that when the treadle is released the leverresumes its former position. The connecting-rod is provided near itsupper end with a hinge-joint, b, and at or about the level of the top ofthe stone with an open frame, 0, connecting the upper and lower sectionsof the said rod, for a purpose hereinafter set forth.

F indicates a rod of suitable rigidity, con nected to the lever D by auniversal joint, 0 c, at a point between its power end and the spring S,and depending vertically directly over the stone.

The article to be smoothed is laid upon the lap or bed and the conicalend of the rod F engaged in areoess of the work by depressing (Model.)

the treadle. A backward and forward motion, changeable at pleasure intoa vibratory motion through the universal joint, may be then imparted tothe said rod, drawing the work over the stone.

G indicates a pitman coupled to vibrate vertically to an offset, 61,011rod F at one end, andat the other, by means of a strap, e, to the wristc of a crank, H, so as to vibrate horizontally. The crank H is keyed ona shaft, J, operated by suitable gearing, and imparts a push-and-pullmovement to rod F, which, through the universal joint in the said rodand the hinge-joint in the wrist end of the pitman, may be arbitrarilychanged to a combined push-and-pnll and vibratory motion when requisite.

The pitman extends through the frame of the connecting-rod, and may workboth vertically and horizontally without interfering therewith.

' What I claim as new, and desire to secure by Letters Patent, is-- 1.In a machine for flatting metal plates and other like objects, thecombination, with the lap or bed (3, of the rod F, suspended by auniversal joint to a lever, D, the spring supporting said lever, theconnecting-rod D,

and treadle E, substantially as specified.

2. The combination, with the lever D, pivoted to the roof or othersupport, the headed rod a, the spring S on said rod below the saidlever, and a table, A, supporting a lap or stone, 0, of the rod F,universally jointed to said lever over the stone, and provided with theoffset (1, the connecting-rod hinge-jointed to said lever D, the treadleE, the crankshaft J, having a driving-pulley and a crank, H, and thepitman G, pivoted to vibrate vertically to the offset and to vibratehorizontally to a strap, 0, encircling the wrist of the crank,substantially as specified.

3. The combination, with the stone or lap, of a rod, F, universallyjointed to a springsupported lever, a mechanism depressing said lever,and a mechanism vibrating the said rod rectilinearly, substantially asspecified.

In testimony that I claim the above 1 have hereunto subscribed my namein the presence of two witnesses.

ALFRED HENRY OLEAVES.
